Hi there, I'm torn between these 2 laptops, a bigger 17.3" screen but apparently slower video card or a smaller 15.6" screen and apparently faster video card. Although the clock speed of the Radeon HD 7450M says it's 700 MHz the Radeon HD 6620G @ 400 MHz is faster in 3dmark? I like a big screen for a nice wallpaper and gaming as well. The 17" HP is 50 bucks off @ $650, the 15" HP @ $550... what do?
